Simcard is not detected several times

[Wurstking]

Since the update to 7.1.1 the Simkartenslot crashes regularly. At least 2 times a day. The phone I always have to restart. Even a resett on the factory setting has brought nothing.

I have simliar issue, my SIM card 1 will be not detected after using the phone for a while. Reboot can temporarily fix the issue.
